Have you ever noticed your iPhone slowing down or running out of memory even when you are not downloading new apps? If you’re wondering why, it could be because of the cached data accumulating on your phone.
When you’re experiencing performance issues on your phone, one of the most common tips is to clear your cache. But how do you do that? To help you restore your phone’s normal speed, this article will explain how to clear the app cache on an iPhone.
What Are App Caches?
App caches are temporary files generated by mobile apps to speed up the loading times and overall performance of the application. Those files usually contain images, data, fonts, videos, audio files, etc. They can also allow applications to be used offline or in slow network conditions.
Cache data consists of instructions and resources that are either fetched from or transmitted into the Random Access Memory (RAM).
When your phone’s processing core requests data, it first checks the cache to see if the data it needs is available there. If the data is present, the processing core can retrieve it faster than having to get it from the RAM.
However, there is one issue. Cache data accumulates over time and takes up space on your iPhone storage. The building up of this data results in performance issues on your phone.
Note: When a smartphone finds the data it needs from the cache memory, it is called a “cache hit”. If the data is not cached on the phone’s local memory, the processing core retrieves it from the RAM, which is called a “cache miss”.
How to Clear Cache on an iPhone Without Deleting Apps
Important: One of the most common ways of deleting an app cache on an iPhone is using the “Offloading” feature. However, it is worth noting that although temporary, the “Offloading” feature still deletes apps you rarely use. While the option retains the deleted app’s data, you have to reinstall your apps if you want to use them again.
There are three methods to clear the cache on an iPhone:
Method 1. Clearing Cache on Safari
